Hi guys,

I have a CX500 PSU in my build at the moment. I currently have a 4690K which I have OCed to 4.2GHz stable. I also have a GTX970 Gigabyte G1 Gaming Edition (Windforce).

Basically the question I'm asking is;

I want to clock my CPU to 4.6GHz but I am unsure as to whether I should risk it with this PSU. I do intend on getting a better one at some point but would like to know whether I'm well within my limits to crack on the with the OC now. When it comes to Power Supplies and Wattage/Voltage, I'm not very clued up.

Below are some screenshots of temps and voltage, etc, in case this might be of use to anyone answering my question;

Most people seem to talk crap about the CX PSU's, but my cx500m is either some golden sample or people talk nonsense. My 6600k is running at 4.5ghz currently, and is completely stable, I've run Aida 64 and cinebench cpu test back to back for about an hour and had no crashing

The problem with CX PSU's is there low quality components which lead to sudden failures and poor protection circuits which means when they do fail there is increased risk of damaging other components. When they go pop its often very sudden.

For the sake of very little money do yourself a favour and get a decent quality PSU. The more you overclock the more load you put on the PSU

The extra overclock will probably pull another 20W to 30W from your power supply.
Although it says 500W, that budget power supply is probably only good for 350 to 400W (I have one too!)
Use an online power supply calculator to find out how much spare power you have...

Also ask yourself if that extra overclock will make you enjoy using your PC more... except for rendering video I can't tell the difference since I overclocked mine

Thanks for the answers guys, tbh with you I probably wont gain any benefit performance wise in terms of my daily usage (Gaming basically), but I enjoy the thought of seeing how far I can push my CPU, PC building has fast become a beloved hobby of mine, though I'm fairly new to overclocking.

I take it the general consensus is to wait it out and save up for a new PSU? If so what would you suggest? I don't think I will need more than 650W and I'd love for it to be fully modular.

Again, thanks guys!

The consensus seems to be EVGA supernova PSU
I am going to wait until my CX500 fails before I upgrade....

Funnily enough I was doing some research earlier and a lot of people are saying that the Supernovas aren't to great either, the parts inside aren't that great and they're overpriced, again, supposedly.

Lets hope your PSU doesn't take anything else with it if it dies ;)

The score in our family so far is THREE failed power supplies and no other components broken....All on ASUS motherboards BTW,
All of those PSU were really nasty no name secondhand old PSU from before I knew better. None of my four Corsair PSU have failed yet
